Hostname & hosts file update
To reduce chance of incidents when instances try to resolve their own hostname using old private traveloka.com zone records (see https://29022131.atlassian.net/browse/TOSD-4062), Site-Infra has updated internal hostnames and /etc/hosts files of a group of instances to ensure they refer to themselves using new hostname ending with .main.tvlk.cloud.
Impact:
- change of internal hostname: Datadog will send metrics under new name, please update your dashboards accordingly
- ensuring new hostname is in the instance's /etc/hosts file: no known risk
Resources:
- update hostname:
- i-110c379f: captchabreaker-app-01.traveloka.com. to captchabreaker-app-01.main.tvlk.cloud
- i-d4b1a370: captchabreaker-app-02.traveloka.com. to captchabreaker-app-02.main.tvlk.cloud.
- add hostname to /etc/hosts of:
- i-0ea4be80 acis-app
- i-f1a4be7f acis-app
